From The Associated Press: A massive dust storm has swept into the Phoenix area and drastically reduced visibility there. The FAA said on its website that Phoenix-bound flights from Las Vegas and LA weren't allowed to leave those airports until 9 p.m. Tuesday. (July 5)

From Russia Today: These amazing pictures from the United States show a wall of dust moving through the city of Phoenix in Arizona. Sandstorms like this happen during the region's monsoon season, which is underway. They occur over desert land and can reach thousands of feet into the air, spurred by strong winds. The dense cloud dramatically reduced visibility, grounding flights at a major airport and leaving thousands without electricity.
